Information processing apparatus and method, and program
The present technology relates to an information processing apparatus and method, and a program that enable more efficient edit. The information processing apparatus includes a control unit that selects and groups a plurality of objects existing in a predetermined space, and changes the positions of the plurality of the objects while maintaining the relative positional relationship of the plurality of the grouped objects in the space. The present technology can be applied to information processing apparatuses.
1. An information processing apparatus comprising
a control unit comprising a processor, the control unit configured to select and group a plurality of objects existing in a predetermined space, and change positions of the plurality of the objects while maintaining a relative positional relationship of the plurality of the grouped objects in the space,
in a case where two of the objects are grouped, the control unit changes positions of the two of the objects while maintaining a relationship in which the two of the objects are symmetrical with respect to a predetermined axis in the space.
2. The information processing apparatus according to claim 1 , wherein the control unit groups a plurality of the objects not having positions in the space, and gives positions to the plurality of the grouped objects in the space.
3. The information processing apparatus according to claim 1 , wherein
in a case where two of the objects are grouped, the control unit changes positions of the two of the objects while maintaining a relationship in which the two of the objects are symmetrical with respect to a predetermined plane in the space.
4. The information processing apparatus according to claim 1 , wherein
the control unit groups two of the objects not having positions in the space, and gives positions to the two of the objects in the space so that the two of the grouped objects have a positional relationship symmetrical with respect to a predetermined axis in the space.
5. The information processing apparatus according to claim 1 , wherein the control unit groups a plurality of the objects having positions in the space.
6. The information processing apparatus according to claim 1 , wherein
on a basis of a position of the object at a predetermined time point and a position of the object at another time point different from the predetermined time point, the control unit obtains, by interpolation processing, a position of the object at a time point between the predetermined time point and the another time point.
7. The information processing apparatus according to claim 6 , wherein
the control unit performs the interpolation processing by an interpolation method selected from among a plurality of interpolation methods.
8. The information processing apparatus according to claim 1 , wherein
in a case where positions of a plurality of time points different from each other of the object are selected and change of positions is instructed, the control unit simultaneously changes selected positions of the plurality of time points by a specified change amount.
9. The information processing apparatus according to claim 1 , further comprising
a display control unit that controls display of an image of the space in which the object is arranged with a predetermined position in the space as a viewpoint position.
10. The information processing apparatus according to claim 9 , wherein
the display control unit causes the object belonging to a same group to be displayed in a same color on the image.
11. The information processing apparatus according to claim 10 , wherein
the display control unit causes the object to be displayed on the image in a color selected for an audio track corresponding to the object.
12. The information processing apparatus according to claim 10 , wherein
the display control unit causes the object to be displayed on the image in a color selected for an audio track corresponding to the object and a color defined for a group to which the object belongs.
13. The information processing apparatus according to claim 10 , wherein
the display control unit causes only the specified object among the plurality of the objects existing in the space to be displayed on the image.
14. The information processing apparatus according to claim 1 , wherein
the object is an audio object.
15. An information processing method comprising
by an information processing apparatus, selecting and grouping a plurality of objects existing in a predetermined space, and changing positions of the plurality of the objects while maintaining a relative positional relationship of the plurality of the grouped objects in the space,
in a case where two of the objects are grouped, the information processing apparatus changes positions of the two of the objects while maintaining a relationship in which the two of the objects are symmetrical with respect to a predetermined axis in the space.
16. A program stored on a non-transitory computer readable storage media that causes a computer to execute processing including a step of
selecting and grouping a plurality of objects existing in a predetermined space, and changing positions of the plurality of the objects while maintaining a relative positional relationship of the plurality of the grouped objects in the space,
in a case where two of the objects are grouped, a control unit changes positions of the two of the objects while maintaining a relationship in which the two of the objects are symmetrical with respect to a predetermined axis in the space.
